My present invention has to do with imdate the enlargements, all of. whichwill' approvements in the type of windshield for 1110- pear clearly from Fig. 4:. A spindle 15 is jourtor vehicles and the like disclosed in my conaled within suitable bearings in'zthe casing pending application Serialllo. 128,576, filed at about the transverse center thereof and t August 11, 1926, and relatesfurther to operformed integral with or secured to the spindle ating mechanism therefor, said mechanism is a pinion 16 which meshes with the racks 12. being adapted for use as well with Windshields The spindle projects rearwardly of the casthat are hingedlyv supported in the ordinary ing and has applied to it an operating handle manner.

A cover 18 is secured to the rear sideof vide efficient, reliable and durable mechanism the casing 10, as by screwsthat are accommo= for adjusting the windshield, that is particudated by holes19 in the casing, appearing in 15 larly easy and convenient of use, which effects Fig. 1. The casing, in turn, is fastened to a quick'adjustment, and that positively holds the adjacent member of the frame-1 byfasthe windshield in any of its adjusted positening means 20', such as screws, that'are entions: l i gaged through apertured lugs 21 thatproject The foregoing objects, with others hereinfrom opposite ends of the casing.

tional plan view of a modification.- shanks of the swivel heads that'extend into The front frame of the vehicle b0dy,-whi ch bores of the'block's 28 inwardly of the sockets. surrounds the windshieldopening, is des1g- The windshield sash is designated 35', and

nated 1. This frame joins the top 2 atits to the inner sides of the top and bottom mem- 35 upper edge, corner posts 3 at its lateral edges, bers of the sash frame are secured blocks 36 3 while the cowl i extends forwardly from its within which are mounted swivel heads 37 lower edge; The top 2 is shown as extended like those previously described. The swivel forwardly of the frame l to provide a, visor heads 29 and 37 are bifurcated, and links 38 5 that is supported at its ends, iii-the usual :have -their' opposite ends engagedwithin the manner, by brackets 6. v bifurcations of said headsand pivoted upon Secured" to the top and bottom members of pins'39 that extend through the heads." The the frame 1 aresubstantially identical windwindshield sash'is' thus connected to the op shield. operating mechanisms each of which crating mechanisms at top and bottom. To includes a casing 10. This casing is shown as support the sash at a proper elevation, trunof material Within the rear face of which are ners ofits frame through slots 11 in the milled or otherwise formed .ways 11 within brackets 6, and these trunnions may be which racks 12 are guided, the racks being equipped with rollers or other anti-friction enlargedat'one of their ends, and theways bearings in accordance with common me- The casings 10 are enclosed within sheaths 43 that are applied to the top and bottom members of the frame 1. Strips 44 of suitable packing material, such as rubber, are arranged about the outer side of the frame 1, and when the sash 35 is in closed position it bears against saidstrips thereby to efiectively seal the oint between the sash and frame. To hold the mechanism in any position to which it isadjusted provide one or more spring pressed plungers 46. which engage within depressions 47 .on the hub. of the operating handle or crank 17 said plungers with their springs being contained within housings 48 that are secured to the cover 18 of the casing 10.

By turning one of the handles or cranks 17, the racks 12 of the corresponding mechanism will be reciprocated within thecasing thereby to move the blocks 28 that are carried by-said racks in and out so. as to correspondingly move the. inner ends of the links 38 and through them adjust the adjacent edge of the sash 35 toward andfrom the frame. During theadjustmentsthe sash is maintained ata proper elevation by the engagement of its trunnions 40. within the slots 41 of the visor brackets 6. The links 38 ofthe lower adjustingv mechanism are preferably longer than those of the top mechanism so that the lower edge of thesashmay be thrown a considerable distance forwardly of the frame 1, as inclicated in dotted lines in Fig. 1, thereby to. permit vision beneath the sash if such becomes necessary because of a coating of rain, sleet orice on the windshield.

It is evident from what has been described that the adjusting mechanism is adapted for use with Windshields thatare hingedly connected. at their upper edges to the windshield frame. This condition is virtually present in the. disclosed construction when only the lower mechanism is operated because under such circumstancesthe windshield swings at its upper end on its trunnions 40. v

It will beseen that in this case, as in the con struction which constitutes the subject matter of my former application above referred to, thesash may be adjusted toward and; from the frame ateither topor bottom or both toefliect ventilation at either or both of these points.

In Fig. 5 I- have disclosed a modification of the adjusting mechanism wherein screws 12? are substituted for the racks 12 of'the pre- Vious form andoperatingupon'saidscrews are blocks 28 which areconnected, through links 38?, to the windshield sash 35 Secured to the inner ends of the screws 12 are beveled pi'nions 5.0 which mesh with a similar pinion 51 carried by the forward end ofa spindle 15. An operating handle or crank 17 is secured to the end: of the spindle 15 where it protrudes beyond the. rear, face of the sheath 43. By meansofthe handle 17 a the screws 12 may be rotated to feed the blocks 28*. in-

wardly and outwardly thereby to adjust the sash 35 through the intervention of the links 38 This construction has the advantage of positively holding, by virtue of the screws 12*, in any position to which the mechanism is adjusted without the need of additional locking means, such as the plungers 46 of the previously described, form.
